Ion channels are pore-forming proteins that help establish the small voltage gradient that exists across the membrane of all living cells (see cell potential) by allowing the flow of ions down their electrochemical gradient. Full article >>>
Ion channels are present in the membranes that surround all biological cells. By conducting and controlling the flow of ions, these pore-forming proteins help establish the small negative voltage that all cells possess at rest (see cell potential). Full article >>>
Ion channel in a membrane that opens and closes in response to changes in membrane potential (voltage); the sodium and potassium channels of neurones are examples. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ... Full article >>>
Many ion channels open or close in response to binding a small signaling molecule or "ligand". Some ion channels are gated by extracellular ligands; some by intracellular ligands. Full article >>>

Use of a CyP-D fusion protein as affinity matrix has revealed that CyP-D binds very strongly to 1:1 complexes of the voltage-dependent anion channel (from the outer membrane) and adeninenucleotidetranslocase (inner membrane). Full article >>>
